absl::StrFormat

template<typename... Args>
[[nodiscard]]
std::string
StrFormat(
    FormatSpec<Args...> const& format,
    Args const&... args);

Description

Use it as you would sprintf(). StrFormat() is the primary formatting function within the str_format library, and should be used in most cases where you need type-safe conversion of types into formatted strings.

The format string generally consists of ordinary character data along with one or more format conversion specifiers (denoted by the % character). Ordinary character data is returned unchanged into the result string, while each conversion specification performs a type substitution from StrFormat()'s other arguments. See the comments for FormatSpec for full information on the makeup of this format string.

Example:

std::string s = absl::StrFormat( "Welcome to %s, Number %d!", "The Village", 6); EXPECT_EQ("Welcome to The Village, Number 6!", s);

Returns an empty string in case of error.
